On the night of September 20, 1997, 78-year-old John Henry Sepeda was at his home in Port Arthur, Texas, asleep in a room with his wife and grandson. The quiet of the night was shattered when an intruder, Elroy Chester, broke into their residence. Chester, who often cut phone lines and unscrewed security lights before his home invasions, moved through the house, rummaging for valuables. The disturbance woke Mr. Sepeda.
As he started to get out of bed to confront the masked intruder, Chester fired a single shot, killing the elderly man. Before fleeing the scene, Chester robbed Sepeda's wife of her ring. This violent act marked the beginning of a reign of terror that would grip the Port Arthur community for months.
In the initial stages of the investigation into John Henry Sepeda's murder, law enforcement pursued leads that resulted in the arrest of several other individuals. In November 1997, five suspected gang members were taken into custody and charged in connection with the crime. By January of the following year, a grand jury indicted three of these men—David Lieby, Michael Lieby, and Arthur Jupiter—for capital murder. However, these charges were ultimately dismissed in February 1998. The true perpetrator, Elroy Chester, was still at large, continuing a violent crime spree that included multiple burglaries, sexual assaults, and other murders. It wasn't until Chester's arrest for a different, high-profile crime that his confession would finally bring clarity to the Sepeda case and exonerate the men who had been wrongfully accused.
The resolution to the murder of John Henry Sepeda came as part of the unraveling of a larger, more terrifying series of crimes. Elroy Chester was arrested in February 1998 for the murder of a local firefighter, Willie Ryman III, whom he had killed after sexually assaulting Ryman's two nieces. While in custody, Chester began to confess to a multitude of other crimes he had committed between August 1997 and February 1998. Among his confessions was the detailed admission to the murder of John Henry Sepeda. Chester pleaded guilty to the Ryman murder and, during his punishment hearing, confessed to four other killings, including Sepeda's. For his crimes, a jury sentenced Elroy Chester to death. On June 12, 2013, Chester was executed by lethal injection, bringing a final and definitive end to the case of the murder of John Henry Sepeda and the numerous other violent acts he perpetrated. The case overview shows a tragic home invasion that resulted in murder, an initial investigation that focused on the wrong suspects, and the eventual capture of a serial killer whose own confessions brought the true and full scope of his violent spree to light.
